A neuromorphic device may include: a plurality of pre-synaptic neurons; row lines extending in a row direction from the plurality of pre-synaptic neurons; a plurality of post-synaptic neurons; column lines extended in a column direction from the plurality of post-synaptic neurons; a plurality of synapses arranged at intersections between the row lines and the column lines; a plurality of first control blocks; and first control lines extending from the control blocks. The first control lines may be electrically connected to the plurality of synapses.
